"Matter waves and electricity."; Lanczos, Cornelius.
The author describes how particles may be resonances in the zero-point vacuum fluctuations. This is similar to the idea that particles may actually be standing waves of electromagnetic energy.
In the scalar electromagnetics view, a mass particle is identically trapped, standing scalar wave resonance. Currents of this scalar resonance (i.e., R-dot) can be generated. A macroscopic mass acts as an accumulator, and can be charged and discharged. Hence the mass and inertia of an object can be deliberately increased or decreased by using R-dot currents to charge or discharge that object.
